Matter Flashcards
Anything that occupies space and has mass.
Matter
The sequence of matter
Matter-Atoms-Atomic Nucleus- (Proton + Neutrons) - Nucleons
Matter-Atoms-Electron Shell-Electrons
Collective term for protons and neutrons are the particles found in the nucleus of atoms.
Nucleons
Classification of Matter
Element
Compound
Mixture
What is an element?
➢simplest form
➢ one (1) kind of material
➢PURE chemical substance
What is a compound?
➢ 2 or more elements are chemically combined in definite proportion
What is a mixture?
➢2 or more substances that are not chemically combined
➢individual identities are retained
Classification of Mixture
Homogeneous
Heterogeneous
Homogeneous
1 phase solution
Heterogeneous
2 phases: suspension and colloids
Properties of Matter
